Abstract: A wireless telecommunications system includes a selection distribution unit (SDU) for receiving high speed data. The high speed data is stored in a buffer queue within the SDU prior to allocation of high speed data resources by a base station controller. Signaling between the base station controller and the SDU ensures that high speed data resources are not prematurely released. More particularly, constant monitoring of high speed data levels within the buffer queue triggers specific signaling from the SDU to the base station controller to guide the allocation of high speed data resources.

Abstract: A method for improving the throughput of a communication system by decreasing the amount of time it takes to retransmit information determined to have been erroneous. Information received by an equipment is decoded and subjected to error detection techniques. The equipment performs a data puncture operation on the received information it is currently transmitting to request a retransmission of such received information.

Abstract: An apparatus for reducing power amplifier headroom in a wireless transmission system comprises an orthogonal modulation circuit and a phase rotation circuit c oupled to the orthogonal modulation circuit. The orthogonal modulation circuit utilizes a Walsh code for modulating an in-phase signal and a quadrature signal. The orthogonal modulation circuit has an in-phase output and a quadrature output. The phase rot ation circuit rotates phase of the in-phase signal the quadrature signal, producing a phase rotated in-phase signal abd a phase rotated quadrature signal. Multiple Walsh co de defined channels are associated with a particular wireless user.

Abstract: A variable length sequence number is used to identify data units in a communication channel. The sequence number associated with the most recent data that has been received successfully and the sequence number expected with the next new data message to be received are examined to determine the minimum size sequence number necessary to unambiguously identify to the transmitter incorrectly received data that must be retransmitted in a later message. The receiver provides the transmitter with the sequence number associated with the last successfully received byte of data and the sequence number associated with the next expected byte of data. The receiver communicates this information to the transmitter using a NAK control message. The transmitter then uses the sequence number of the next byte of data to be transmitted and the information received in the control message from the receiver to determine the smallest number of bits necessary to represent the sequence numbers for both data transmissions and the retransmission of data that was not received properly by the receiver.
